Abstract (en)
[origin: WO2022146442A1] A rubber composition having improved antiozonation performance comprising a substituted quinoneimine form of substituted p-(hydroxy)phenylamine. Such a composition is particularly suitable for rubber articles. The improved rubber composition possesses a long lasting antiozonation performance, slowing migration through the rubber article and reducing effluence of the antiozonant. Such rubber articles may include rubber pneumatic tires, solid tires, non-pneumatic tires, belts, hoses, cables, automotive mounts, bushings and general mechanic products that are exposed to continuous and intermittent dynamic operation conditions and require protection from ozonation.
